DUSTLESS COAL OR FLOUR SIFTER.

SPECIFICATION forming part of Letters Patent No. 549,019, dated October29, 1895.

Application filed June 15, 1895- To all whom it may concern.-

Be it known that I, JOHN L. RAPPLEYEA, a citizen of the United States,residing at the city of Newburg, in the county of Orange and State ofNew York, have invented a new and useful Dustless Coal and Flour Sifter,of which the following is a specification.

My invention relates to improvements in sitters, and has for its objectto provide asifter which will be comparatively dustless in itsoperation, and which is simple in construction, and which may be readilycleaned or repaired when necessary.

My invention will be better understood by reference to the accompanyingdrawings, wherein the same parts are indicated by the same lettersthroughout the several views.

Figure 1 is a perspective View of my improved sifter,'one of the hingedcovers being raised to show the screen. Fig. 2 is a central longitudinalvertical section through the same. Fig. 3 is a vertical cross-sectionthrough the same. Fig. 4 is a plan view of the metallic blank from whichthe outlet-door is made, the dotted lines indicating where the blank isfolded in order to fit over the end of the bottom trough; and Fig. 5 isa similar view of the blank from which the bottom trough or receptacleis made, the inner dotted lines indicating where the blank is folded tomake the sides of the trough and the outer dotted lines indicating wherethe blank is folded to make the flanges upon the sides of the trough, bymeans of which the trough is secured to the bottom of the upperreceptacle.

My sifter is composed of a rectangular box or receptacl into which theashes or flour to be sifted is poured, and a metallic trough open at oneend for emptying the same is secured to the bottom edges of thisrectangular box by means of screws passing through flanges on saidtrough, and the screen for sifting the material is held between theflanges on the bottom trough and the bottom edges of the upper box orreceptacle, as will be hereinafter more fully described.

The upper box L is provided with hinged covers 0 and e, and a stripw issecured along the edge of one of said covers in order to make a tighterjoint and prevent the escape ofdust. The box is provided with end piecesm and p, sloping as shown, and at one end is Serial No. 552,894.. (Nomodel.)

provided with a. handle for shaking the sifter.

The bottom trough b is made with a flange around three of its sides andis open at one end to allow the sifted material to be emptied. Thisflange is perforated to admit screws for securing the trough to theupper box, as shown in Figs. 2 and 3.

The screen it is held between the flanges on the bottom trough and thebottom edges of the upper box or receptacle, and the screws passingthrough the flanges on the said bottom trough also pass through themeshes of the screen along its edges and securely hold the said screenin position; but it will be seen that the said screen may be readilyremoved for the purposes of cleaning, repairing, 860., by simply takingout the screws. 7c

A door 01, made so as to fit over the end of the bottom trough, ishinged beneath one end of the upper box, and when closed engages a catchon the trough, which holds the said door closed.

In operation the ashes or other material to be sifted are poured intothe box or receptaole L and fall upon the screen h, the door at beingkept closed. By agitating the sifter by means of the handle is the finematerial will fall through the screen and down into-the bottom trough b.When the bottom trough becomes full, or when all the material has beensifted, the outlet-door 01 may be opened and the sifted material pouredout. The larger particles will remain upon the screen and may be emptiedby tilting the sifter.

It will be seen that I provide a neat, cheap, and efficient device forsifting coal-ashes, flour, or any other substance that would ordinarilyrequire to be sifted in a household.

It will be seen that the screen being readily removable, severaldifferent grades of screens may be made to accompany each sifter, and afine or a coarse screen may be used, according to the material to besifted.

Having thus described my invention,what I claim, and desire to secure byLetters Patent of the United States, is-

In a sifter of the character described, the combination with therectangular box L, having hinged lids c and e forming an approximatelydust tight cover therefor, of the metallic trough I; having flangesalong three of its upper edges by means of which flanges the said troughis secured to the box Lby screws passing through said flanges, the saidtrough being open at one end for the discharge of its contents; the door(1 hinged to one end of the box L and adapted to close the open end ofsaid trough b; the metallic screen h held along its edges between thesaid trough b and the said box L, and a handle by means of t which thesifter may be agitated, substan- IO tially as described.
